I just installed CUDA 7.0 and generated the **OpenCV** makefiles for **VisualStudio 2013 x64** through CMake. While building in the Debug configuration in VS2013, I have tons of warnings like these and its taking hell longer then it would normally take without **WITH_CUDA** checked in CMake.
I got the following:
C:\opencv-master_2\opencv-master\modules\core\include\opencv2/core/cuda.hpp(494): warning : field of class type without a DLL interface used in a class with a DLL interface How do I resolve the warnings??
There are many of these:
